Itu prinsip dari laser rentang teknologi menggunakan fase metode dan pulsa metode untuk laser pengintai
Itu genggam laser pengintai D5 adalah dirancang untuk luar ruangan pengukuran pekerjaan dengan beberapa pengukuran fungsi% 2c termasuk a ganda zoom digital penglihatan% 2c a a 2.{{2% 7d% / 7dinch warna tampilan layar saat kemiringan sensor. The 4x zoom digital penglihatan memungkinkan Anda untuk cepat tujuan at jauh target dan bisa juga digunakan dalam cerah luar lingkungan. In lingkungan di mana laser titik tidak bisa dibedakan dengan the telanjang mata, Anda bisa dengan mudah Identifikasi laser titik melalui A 2.4-INCH definisi tinggi warna tampilan layar untuk akurat jarak jauh pengukuran.
Laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance of a target. It is lightweight, small in size, easy to operate, fast and accurate, and its error is only one-fifth to one hundred times that of other optical rangefinders. The world's * * laser is the first ruby laser developed by scientist Mayman from Hughes Aircraft Company in 1960. The US military quickly conducted research on laser devices based on this foundation. In 1961, * * * laser rangefinders passed the US military's demonstration test, and after this, the laser rangefinders quickly entered the practical stage. Due to the continuous decline in the price of laser rangefinders, they are gradually being used in industry. A batch of new types of micro rangefinders with advantages such as fast ranging, small size, and reliable performance have emerged both domestically and internationally, which can be widely used in industrial measurement and control, mines, ports, and other fields.
Itu arus utama laser pengintai in saat ini pasar adalah berbasis pada fase metode. Ini adalah karena laser rangefinders berbasis pada fase metode dapat dengan mudah mengatasi a mayor kekurangan dari ultrasonik rangefinders% 3a berlebihan kesalahan% 2c hasil dalam pengukuran akurasi mencapai milimeter level. The main kekurangan dari laser rangefinder berdasarkan pada ini metode are kompleks sirkuit dan pendek pengoperasian jarak (sekitar 100 meter, setelah upaya dari banyak ilmiah pekerja, ada adalah sekarang fase berbasis laser pengintai dengan pengoperasian jarak dari beberapa ratus meter).
The phase method laser ranging technology uses a laser with a radio frequency band to modulate the amplitudo and measure the phase difference generated by the distance between the sine modulated light and the target object. Based on the wavelength and frequency of the modulated light, the laser flight time is calculated, and then the measured distance is calculated in sequence. Ini metode umumnya membutuhkan penempatan a reflektor at objek to be diukur, reflektif the laser path back to the laser rangefinder, and menerima dan pemrosesan it by the diskriminator dari the menerima modul. That is to say, this method is a passive laser ranging technology with cooperative target requirements.

The phase method is similar to the method used for ultrasonic velocity measurement and distance measurement. The large measurement distance is usually several hundred meters, which can easily reach the order of millimeters. Namun, the large measurement distance of the distance measuring instrument designed according to this method is limited and cannot be extended. This method is terutama widely used abroad. Pulse laser ranging generally uses infrared laser, include near-infrared laser and mid infrared laser. There are visible and invisible lasers in this band. And the rangefinder based on this technology has low requirements for coherence, fast speed, simple implementation structure, high peak output power, high repetition frequency, and large range. Therefore, this project uses the pulse method to design a handheld laser Rangefinder.
